The graduate program in Primate Behavior at Central Washington University provides the only opportunity for students to earn an MS degree in Primatology in the United States.

The program focuses on interdisciplinary, problem-oriented, broad-spectrum knowledge relating to primates, with a particular focus on conservation issues. Students entering the program will be exposed to coursework and practical experience in the areas of anthropology, biology and psychology and will have opportunities to conduct sanctuary, zoo, and/or field research under the guidance of faculty mentors. The program serves students who will enter the work force for employment in sanctuaries, zoos, field research, conservation agencies, or teaching, or who will continue on to Ph.D. programs.

This collection features theses from Master of Science students in the Department of Primate Behavior Graduate Program at Central Washington University.
